In C#, value-type parameters are that pass a copy of original value to the function rather than reference. It does not modify the original value. A change made in passed value does not alter the actual value. In the following example, we have pass value during function call.
using System; namespace CallByValue { class Program { // User defined function public void Show(int val) { val *= val; // Manipulating value Console.WriteLine("Value inside the show function "+val); // No return statement } // Main function, execution entry point of the program static void Main(string[] args) { int val = 50; Program program = new Program(); // Creating Object Console.WriteLine("Value before calling the function "+val); program.Show(val); // Calling Function by passing value Console.WriteLine("Value after calling the function " + val); } } }
